Abstract
The utility model discloses a dehumidifying and drying device of a humidity transducer. The utility model realizes the dehumidification and the drying of air in the humidity transducer in a non-test state, so the humidity transducer is protected. The utility model has the advantages that the humidity transducer is effectively protected, and the cost is low. The utility model is structurally characterized in that the dehumidifying and drying device comprises the humidity transducer, the air outlet end and the air inlet end of the humidity transducer are respectively communicated with the atmosphere and the test air through a pipeline with a controller, and at the same time, at least one drying device is arranged and connected between pipelines arranged between the air outlet end of the humidity transducer and the control device corresponding to the gas outlet end.
Description
Technical field
The utility model relates to a kind of humidity sensor dehumidification drying device.
Background technology
At present, when adopting humidity sensor to test, if test gas is a high humidity gas, under trystate, control device is opened simultaneously, and test gas passes through humidity sensor; Off-test, control device cuts out simultaneously, and high humidity gas is sealed in the humidity sensor.If place a period of time at the off-test state, especially under low temperature environment, store a period of time, the high humidity gas in the humidity sensor may form aqueous water; At this moment, give the humidity sensor energize, will produce very big electric current, even short circuit occurs, thereby shorten the life-span of sensor or damage sensor.
Summary of the invention
The utility model provides a kind of humidity sensor dehumidification drying device for overcoming above-mentioned the deficiencies in the prior art, and it can be to the humidity sensor removal moisture drying, thereby humidity sensor is played a protective role.
The purpose of this utility model is to adopt following technical proposals to realize:
A kind of humidity sensor dehumidification drying device, it comprises humidity sensor, the outlet side of described humidity sensor and inlet end are communicated with atmosphere and test gas by the pipeline that has control device respectively; Also be provided with pipeline between this end control corresponding device simultaneously and be connected at least one drying device in the outlet side of humidity sensor.
Described drying device is the three-way connection that is built-in with the closed container of drier and connects by pipeline with it, and three-way connection is arranged on the pipeline between the corresponding control device with this end in humidity sensor outlet side.
Described control device comprise be arranged on the valve I on the pipeline between humidity sensor and test gas and be arranged on humidity sensor and atmosphere between valve II on the pipeline.
The hermetically drying structure of the utility model humidity sensor comprises control device, drying device and humidity sensor three parts.Wherein:
Control device comprises valve I and valve II.Valve I, valve II are connected the two ends of humidity sensor, control test gas air blowing and stop the supple of gas or steam.
Drying device is airtight, in drier is arranged.
When control device (valve I, valve II) when being autocontrol valve,, in humidity sensor, blow or stop the supple of gas or steam by the switch of SCM program or computer program control autocontrol valve.
The course of work of the present utility model is: when normally testing, control device (valve I and valve II) is opened simultaneously, and test gas enters atmosphere after by humidity sensor.When off-test, control device (valve I and valve II) cuts out simultaneously, and test gas is sealed in the enclosure space of compositions such as humidity sensor, drying device, control device.When the humidity of test gas was high, under moist gradient, the moisture in the humidity sensor can enter drying device by tube connector, was absorbed by the drier in it, and through drying after a while, the humidity of gas can slowly lower in the humidity sensor.
Advantage of the present utility model is:
1. when control device (valve I and valve II) when being autocontrol valve, to operate simplyr, the labour intensity of testing crew is little.
2. effectively protect humidity sensor.
Description of drawings:
Fig. 1 is a kind of structure chart of the utility model structure;
Wherein, 1. gas circuit pipe I; 2. valve I; 3. gas circuit pipe II; 4. humidity sensor; 5. gas circuit pipe III; 6. three-way connection; 7. gas circuit pipe IV; 8. valve II; 9. drying device; 10. gas circuit pipe V.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Embodiment 1:
In the present embodiment, as Fig. 1, test gas is connected to the inlet end of valve I 2 by gas circuit pipe I 1, the outlet side of valve I 2 is connected to the inlet end of humidity sensor 4 by gas circuit pipe II 3, the outlet side of humidity sensor 4 communicates with three-way connection 6 one ends by gas circuit pipe III 5, the other end of three-way connection 6 is connected to the inlet end of valve II 8 by gas circuit pipe IV 7, and the outlet side of valve II 8 connects atmosphere.The 3rd end of three-way connection 6 is communicated with drying device 9 by gas circuit pipe V 10.
When valve I 2 and valve II 8 are closed simultaneously, valve I 2, valve II 8, humidity sensor 4, drying device 9 grades form an enclosure space, in the enclosure space humidity along with the moisture absorption of drying device internal desiccant diminishes, thereby protected humidity sensor 4.
Claims (3)
1. humidity sensor dehumidification drying device, it comprises humidity sensor, it is characterized in that, the outlet side of described humidity sensor and inlet end are communicated with atmosphere and test gas by the pipeline that has control device respectively; Also be provided with pipeline between this end control corresponding device simultaneously and be connected at least one drying device in the outlet side of humidity sensor.
